Since that time, the tool was refreshed in a beta 2 release and, as of November 13, a full version 1.0 release. Given the deserved popularity of the tool among web developers and search engine optimizers, I wanted to take a moment to explore what has changed with the IIS SEO Toolkit since the beta 1 article was published.

Technical requirements unchanged

This remains unchanged from the first beta release. The tool was built as an extension of IIS 7, so you need to use an operating system that can run IIS 7 in order to run the tool. That means you can run any of the following IIS 7 and higher-compatible operating systems:

Windows Vista Service Pack 1 (and higher — you may need to first upgrade the default version of IIS to 7.0)

Windows 7

Windows Server 2008

Windows Server 2008 R2

Because of the toolkit’s core dependency of running as an extension to IIS 7, Windows XP, which cannot run IIS 7, can’t be used as a platform for the IIS SEO Toolkit.

However, make no mistake about this important point. The IIS SEO Toolkit is a client-side tool. Once it is installed on your computer workstation, you can use it to perform a detailed analysis on your website regardless of the web server platform it uses, be it IIS, Apache, or even if the “site” is simply a collection of HTML and associated files and folders stored locally on your computer.

Install the toolkit

Admittedly, the beta 1 product was a bit complicated for some to install. We got some complaints about it in Bing. But that’s beta software for you! The IIS team developers took your feedback and streamlined the process tremendously for the final release. Now the installation of version 1.0 of the IIS SEO Toolkit is an automated process (click the preceding link to start). You don’t even need to uninstall any beta versions! How cool is that?

There are many improvements here. First and foremost, after installing the new version of the IIS SEO Toolkit, you can start the tool through an icon on your Start menu (I found it at Start > IIS 7.0 Extensions > Search Engine Optimization (SEO) Toolkit 1.0). This provides users with much more intuitive, direct access to the tool.

Other usability improvements include streamlining the query builder interface, the addition of a Violations tab on the Details dialog boxes for direct access to affected pages, new context menus for copying content from the tool, new Help shortcuts, keyboard navigation has been improved, and much more.

Extensibility enhancements

The toolkit has been opened up with a new set of APIs for developers who need to extend the tool’s potential. Now you can create custom modules that can extend the crawling process through augmenting existing metadata reports with your own, parsing new content types, and defining new violations based on user needs. The extensibility even enables developers to add new user interface (UI) elements for both the Site Analyzer and the Sitemaps and Sitemap Indexes tools. For more information on how this feature works, check out the IIS developer team’s blog article IIS SEO Toolkit – Crawler Module Extensibility.

Metadata stored

By using the aforementioned extensibility of the tool, the HTML parser can now store the contents of the <meta> tags from all pages within the analyzed site and use that data for new queries.

Comparison reports

You can now compare two reports side-by-side to track various changed metrics over time from your website. For more information on this, check out the blog article IIS SEO Toolkit – Report Comparison.

Authentication support

The tool’s custom crawler, IISBot, can now crawl secured pages that use either basic or Windows authentication. This will be a significant boon to users who want to use the toolkit on secured intranet sites and on protected staging servers prior to publication.

Canonicalization support

The toolkit supports canonicalization efforts by accepting the use of the rel=”canonical” attribute of the <link> tag. It can look for and identify several new canonical error violations in the site’s code. Support for sub-domain canonicalization is provided. The toolkit also provides link position information for canonical URLs.

Data export options

You can now choose to export a comma-separated-value (CSV) format list of all detected violations, all URLs, or all links from the toolkit.

The routes query is an entirely new type of query, which identifies deeply-linked pages (pages that are buried on your site and require several clicks to finally access from the home page) and more.

Local files cache options

Users now have the option to disable the toolkit from keeping analyzed site files in a local cache. Disabling the cache allows reports to run faster and consumes far less disk space. Note, however, that disabling the cache also prevents the Site Analysis tool from presenting the Content tab from the Details dialog box, disables the contextual position of links, and disables the Word Analysis feature from appearing.

Better robots.txt file handling and management

The Robots Exclusion tool can directly open your robots.txt file for processing.

Better Sitemap.xml handling and management

The Sitemaps and Sitemap Indexes tool has been improved with better filtering and managing of canonical URLs.
